i have tried this so many times.
i take the model for a mosfet (appearing as a box with 3 pins) and try to edit it (to what an actual mosfet looks like), but i CANNOT. orcad just allows me to put the lines/circles and other geometric shapes in specific locations on the grid page.

could anyone help me with this please?

but when i bring an already shaped model, i can open it in the same grid page BUT again i cannot change or reshape it!!!
